I have a work-in-progress branch at https://github.com/lxqt/qtermwidget/tree/wip-qt6. It is far from finished, though.

See also lxqt/lxqt#1901

Qt5LinguistTools is still required by cmake.
_log.txt

[yan12125]

Yep, https://github.com/lxqt/lxqt-build-tools/blob/master/cmake/modules/LXQtTranslateTs.cmake.in is not updated for Qt 6 yet.

[yan12125]

Here comes the first major issue - KPty is not compatible with Qt 6 yet https://phabricator.kde.org/T13940. Although theoretically we can move forward without waiting for KDE devs, nobody in LXQt understands kptyprocess well as far as I know.

[DAP-DarkneSS]

It sounds OK for me to work with KDE.

[Conan-Kudo]

KPty is now ported to Qt6, and at least in Fedora 40, exists as a framework package kf6-kpty.

[yan12125]

Yes, we can now learn from KF6 kpty. There are WIP pull requests at #532 and lxqt/qterminal#1067.

EDIT: use the latest pull request for qtermwidget

[ADebla]

Do you any updates about the PyQt6 full support ?

[yan12125]

Qt6 and PyQt6 are now supported! Although there are still some minor glitches, qterminal and qtermwidget are usable with Qt 6 in general.
